I finished the job with the audio. I couldnt do much but all I heard were screams and the words that I mentioned earlier. I tried several times to isolate the voices but I don't think it's good enough. If you want me to load the audio file isolated just say it.
I also tried to isolate the morse code, I think it repeats several times.
Here's the audio of it. Note that it's a bit quiet.
I don't know morse code so I'm not able to translate it
